IMPROVEMENT IN CAR-STARTERS.

Specification forming part of Letters Patent No. 128,527, dated J uly 2,1872; antedated J une 29, 1872.

SPECIFICATION. To all whom it may concern:

Be it known that 1, ROBERT BOGARDUS, of the city of New York, in thecounty of New York and State of New York, have invented a new and usefulImprovement in Gar-Starters;

and I do hereby declare that the following is afull, clear, and exactdescription of the same,

'reference being had to the accompanyin g drawpulley E, which issubstituted for the grooved pulley E described in said patent No.104,411. Fig. 2 is a side view of the grooved pulley E, showing theshaft or car-axle F. Fig. 3 is a sectional elevation, showing theratchet-wheel A, recess D, and-pawl B. Fig. 4 is a sectional view of thepulleyE.

A is a ratchet-wheel, secured immovably upon the car-axle. B is a pawl.D is a recess, in which the pawl B enters or recedes. E is the groovedpulley, so arranged, as set forth in former patent, to turn freely uponthe aide of the car. F is the axle of the car, to which is secured theratchet-Wheel A, and upon which the grooved pulley E turns. The pulley Eis so constructed as to form a case or cover for the pawl B andratchet-wheel A, which protects them from dust and ice, which protectionisvery important, andis perfectly accomplished by my device, as is shownby Fig. 3. The ratchet-wheel A is arranged to turn freely either waywithin the pulley E when not in contact with the pawl B. The recess Dand pawl B are so arranged and constructed that, when the pulley E is inthe proper position to start the car, as is shown in Fig. 3, the pawl Bwill drop on the ratchet-wheel A, thus causing the power applied to thepulley E to be transmitted to the car-axle. The pulley E revolves withsaid axle until the recess D takes the position shown by the dotted linein Fig. 3; the pulley E is then brought to rest. The pawl B then entersor recedes in the recess D, the construction being such as to preventits being thrown or jarred, so as to again come in contact with theratchet-wheel A. While the pulley E is in that position the car can bereversed, and rattle and wear are prevented. When the pawl B is againrequired, the pulley E is reversed, and,

while returning, the recess D becomes inverted, and the pawl B, by itsown weight, drops into the position shown by Fig. 3. The pulley E andratchet B can be constructed wholly or in sections, bolted or otherwiseput together, so as to be placed on the car-axle without removing thecar-wheels.

Having thus described the construction and arrrangement of my invention,what I claim, and desire to secure by Letters Patent, is

The pawl B and recess D, constructed and arranged to operatesubstantially as described.
